hi, I am reading the description of memcmp and strcmp, it seems there
is no big difference between these two functions. except that memcmp
takes void pointer parameters. so why string.h has these two functions
doing the same thing?

Hi all,
Just browsing through my newly-acquired C99 spec, I was reading on the
memcmp() function (7.21.4.1). It has a rather peculiar wording:
int memcmp(const void *s1, const void *s2, size_t n);
1. The memcmp function compares the first n characters of the object
pointed to by s1 to the first n characters of the object pointed to by s2.

which of the 2 commands are applicable in comparing an array of unsigned chars?
if(strcmp(aAbsCylNumHigh, bAbsCylNumHigh)<=0 && strcmp(aAbsCylNumLow,bAbsCylNumLow)<=0 && strcmp(aSecNum,.bSecNum)<0 )
or
if(memcmp(aAbsCylNumHigh, bAbsCylNumHigh,2)<=0 && memcmp(aAbsCylNumLow,bAbsCylNumLow,2)<=0 && memcmp(aSecNum,.bSecNum,2)<0 )

One way I've seen strcmp(char *s1, char *s2) implemented is: return
immediately if s1==s2 (equality of pointers); otherwise do the usual
thing of searching through the memory at s1 and s2.
Of course the reason for doing this is to save time in case equal
pointers are passed to strcmp. But it seems to me that this could create
an inconsistency in the degenerate case when s1 points to memory that is
not null-terminated, i.e. by some freak...

Please consider the following code fragment. Assume UINT32 is a typedef
suitable for defining variables of 32 bits, and that ui32 is initialised.
UINT32 ui32;
/* ... */
/* assume ui32 now is holding a value in uc's range */
unsigned char uc = (unsigned char) ui32; /* tell Lint you know target
type is smaller */
cmos->uc = uc;

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
